NICECHANISM FOR OPERATING MOLDlNG-IVIACHINES.

SPECIFICATION forming' part of Letters Patent No. 730,313, dated June 9, 1903.

Application iled February 24, 1908'.

To a/ZZ whom it myconcern:

Be it known that' I, FRANK J; STRATTON, a citizen of the United States, residingv at Lagrange, in the county'of Cook and State of Illinois, have invented certain new and usefulA Improvements in Mechanism for Operating Molding-Machinesf which the following is a specication. i

This invention relates to improvements in molding-machines, Yand has for'its principal object to furnish a simple and inexpensive mechanism for easily and accurately lowering and raising the Vpattern-frame and.V has some of the elements shown and described in application, Serial No. 35,728, iiled by me on the 7th day of November, 1900.

My present invention consists in novel features of construction and combination of parts whereby the above object, as Weil as others hereinafter named, are'aceomplished, as will be fully described, and particularly pointed out in claims.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Y Figure l is a view in side elevation of a machine embodying Iny invention, showingA by broken lines the position of the parts when the pattern-frame is lowered. Fig. 2 is a plan View. Fig. 3 is an end View in elevation. Fig. 4 is a sectional view taken on line` 4 '4t' of Fig. 2 looking in the 4direction indicated by the arrows. Fig. 5 is a detached perspective view of a portion of the pattern-carryingV frame or yoke and one of its adj ustable guides, and Fig. 6 is a perspective view of one of the guide-bars detached.

Similar letters refer to like parts throughout the dierent views of the drawings.

A represents the bed-plate, which in the present instanceis shown as being circular, but which maybe of any suitable shape and is provided with a series of openings d and a,the former to permit of the passage of sandand the g latter for the operation of the adjustable snpporting-rods for the pattern-carrying frame. The plate 4vA is supported by means of legs SerialNo. 144,661; (No model.)

A' and has secured to its lower surface hangers B and B', in which are journaled the shafts CgCf, and C2, the shaft C' extending some distance through the hanger B, as is clearly shown in Figs. 2v and 3 of the drawings. Supported on suitable uprights c, eX-

tending vfrom the plate` A upwardly, is the Y stripper-plate D, on which the asks or moldboxes' (not'shown) rest. The inner surface of the stripper-plate D is provided with a number of angular or V-shaped recesses d for the reception and operation of the correspondingly-shaped guides d', which are carried by the pattern-carrying frame or yoke D', which is of a shape to correspond with the shape of the stripper-plate D and is located therein. Secured to the outer surfaces of the plates A and D at points opposite the recesses din the stri pper-plate are bars D2, each of which has on its inner surface a rib d2, provided with a vertical angular recess d3 for the reception and Operation of the guides d on the yoke or pattern-frame. Each of the guides Cl' comprises an upright portion triangular in cross-section and has on its inner surface a horizontally-extending bracket di, which is provided with elongated openings d4 for the reception of bolts d5, located in the yoke D and employed for secu ring the guides thereon. Passing through the yoke D at points opposite the inner surface of each vof the guides d are adjusting-screws di, by means of which the guides maybe moved, so as to cause them to fit the grooves or recesses d and d3 snugly. The lower surface of the pattern-frame or yoke D is provided with a number of lugs e, which are arranged in pairs, as shown in Fig.

3 ofthe drawings, and have pivotally secured between them screw-threaded socket-pieces e', which receive one end of the adjustingrods e2, which rods are provided lwith rightand-left screw-threads and the other ends of Y which engage socket-pieces e3, which are pivotally connected at their lower-ends to other parts, as will be presently explained. Fixed on the shaft Of near oneof its ends is a handle'ver E, used for rocking said shaft when it is desired to raise and lower the pattern-frame or yoke. Rigidly secured to the shaft C' near thelever E is an arm E', which has secured thereto, by means of a pivot e4, a segment-link E2, the other end of which is pivoted on a pin or shaft e5, on which is also pivotally secured an arm F, which is connected, by means of a connecting-rod G, to one end of an arm H, the other end of which is secured, by means of a pivot 72 to the shorter arm h of the lever H', which is fulcrumed on the shaft C. Fnlcrumed on the shaft C2 is a bell-crank lever G', the shorter arm g of which is pivotally secured on the pin or shaft e5, which connects the link E2 and arm F. The longer arm of the bell-crank lever G is pivotally secured to one of the socket-pieces e3, which extends through the openings a in the bed-plate. The longer arm vof the lever H is pivotally connectedl to one of the socket-pieces es, as is clearly shown in Fig. l of the drawings. On the opposite end of the shaft C from that on which the lever H is located is fixed an arm I, which is pivotally connected at its other end to one of the socket-pieces e3, (see Fig. 4,) and on the opposite end of the shaft C2 from that on which the bell-crank lever G is located is fixed an arm I', the other end of which is pivotally secured io one of the socket-pieces e3, which socketed pieces and the rods e2, engaging therewith, are employed for adjusting the position of the pattern-frame or yoke, which can be done by turning the rods e2 inthe proper direction to raise or lower said frame. While I have shown the guides d located so as to extend above the movable yoke or frame D', yet it is apparent that by simply reversing them they may be secured to the lower surface thereof.

By throwing the hand-lever E to the position shown by dotted lines in Fig. l of the drawings it is evident that the movable frame or yoke D through its connections with the power-shaft C', on which the said lever is fixed, will be lowered, thus withdrawing the patterns from the fiasks or mold-boxes.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the supportingframe, of a power-shaft C', and two other shafts C, and C?, journaled thereon, a movable frame within the supporting-frame, a hand-lever fixed on the power-shaft, a lever fulcrumed on the shaft C, and having a long and short arm, a rod pivotally connecting the said longer arm and movable frame, an arm I, fixed on the shaft C, near its other end and pivotally connected to the movable frame, a bell-crank lever fulcrumed on the shaft C2, and pivotally connected by its longer arm to the movable frame, connections uniting the shorter arm of the bell-crank lever to the shorter arm of the lever on the shaft C and to the power-shaft respectively, and an arm I', fixed at one of its ends to the shaft C2, and pivotally connected at its other end to the movable frame, substantially as described.

2. The combination with the supportingframe having vertical grooves or guideways, of a power-shaft C', and two other shafts C, and C2, journaled thereon, a movable frame located within the supporting-frame, guides adj ustably secured to the movable frame, a hand-lever fixed on the power-shaft, a lever fulcrumed on the shaft C, and having a long and short arm, a rod pivotally connecting the said longer arm and movable frame, an arm I, fixed on the shaft C, near its other end and pivotally connected to the movable frame, a bell-crank lever fulcrumed on the shaft C2, and pivotally connected by its longer arm to the movable frame, connections uniting the shorter arm of the bell-crank lever to the shorter arm of the lever on the shaft C and to the power-shaft respectively, andv an arm I', fixed at one of its ends to the shaft C2, and pivotally connected at its other end to the movable frame, substantially as described.

FRANK J. STRATTON.
